v The tool 45 comprises a driving head 41 which is cup-shaped, having an interior recess 48 there- I in. Within the outer portion of the recess 48 Letters Patent is:

transverse ducts 28, 29 are then drilled to pro vide communication between the gas supply groove I5 and the mixing chambers or bores 25, 26 in the inserts. a

It is understood that various changes and modifications may be made in the embodiments illustrated and described herein without depart ing from the scope of theinvention as defined by thefollowi'ng claims. I

Having thus described claimed as new and desired to be secured by 1.--A- tool for assembling torch tips having a plurality of longitudinal bores therein, into which there jis secured the plate through which the 1 V all beingof equal length, lost motion connections rods 50 project. tapered points 5| and enlarged heads 52 The plate 49 is provided with flared openings 54 through which-the shanks ofthe rods 58 extend.

These rods, are provided with 1 The openings 54-are of varying depth, the inner ends of theflared openings being provided with" shouldered abutment portions 53 against which the heads 52 are adapted to seat. "The openings 54 are thus in effect count'ersunk with the countersunk portions thereof stepped so asto extend to various degreesof depth into the plate or block 49.

head 52 of the pin 50 associated therewith-may rest directly upon theinner face of the plate 49 as'indicated in the upper right hand portion of 5 Figure 1. Therods 55 are preferably ofequal length but the stepped recesses into which the heads 52 are adapted to enter provide means for the respective passageways 1 2d; of which there As a matter 'o'fiact, one of the; openings 54 need not be countersunk but the;

are usually :four in cuttingtorchitips of this type i 1 as shown in Figure3. Itwill be-seen that this arrangement greatly facilitates'the introduction of the points of thetool; each successive'pointbeing guided individually into its-proper opening. When-allof the points'are applied, the head I 4] of the tool is moved toward the torch tip whereupon the heads 52 of. the several rods 55 abut I the rearwall of .the recess-was in Figure '4.

Continued movement of thetool 45 toward the torch. tip by suitable. means such as a press,

serves. to force. the -inserts 25, 25' through-the point at the rear ends of the passageways.

swage the forward ends of the inserts 25 .toward the walls of the passageways 2B. and securely and permanently embed them within the torch front end; [0B of the tip. Thetool 45 is then 4 withdrawn and the tip blank is swaged in order toprovide the proper taper, and then the oxygen passageway, and the heating; gas passageways 20 may be rebored at their forward ends. The

are firml'y'seated tubular inserts; said tool comprising a head, a plurality of pins projecting from said head; and movably carried thereby, said pins between-said head and said pins so constructed and arranged that-the movement of said pins with respect" to said; head toward the I work is head. I

an abutment portion on said headfoccupying a singleplane and limiting the retractive movement of said pins, whereby the outer ends of said pins may be individually and successively intro- ';-dll08d into the several bores of the torch and then forced equally therein by;the application of pressure to the head.
